The Hawker PV-3 was a private-venture aircraft designed to Specification F.7/30, which called for a single-seat day interceptor and night fighter with an armament of four Vickers guns and a maximum speed of 250 m.p.h. The PV-3 was the epitome of Hawker’s biplane fighter development and was finally flown on trials in 1935 fitted with a 695 h.p. Rolls-Royce Goshawk engine. The F.7/30 requirement was eventually fulfilled by the Gloster S.S.37 which went into production as the Gladiator.
